A headgear assembly includes a strap of a first flexible material with an elongate edge, and a second flexible material folded around and running along the elongate edge. The second flexible material may be an elastic material. The second flexible material may also cover an intersection or joint in the first flexible material such that the first flexible material may be made from two flexible materials layered together or joined end to end.

An orthopedic hinge assembly is provided, which includes a V-shaped blade, an intermediate blade and a terminal blade. The V-shaped blade, the intermediate blade and the terminal blade are provided with holes to allow a fixed member to pass through; the V-shaped blade is hinged to one end of the intermediate blade for supporting the bending of a body; another end of the intermediate blade is hinged to the terminal blade for supporting the bending of the body; the strip-shaped grooves on the V-shaped blade, the intermediate blade and the terminal blade can be used to fix the orthopedic hinge assembly to a surface of the body using a belt or other fixed member, and to make the corrective member stably fix to one side of the body, effectively producing the lateral corrective force; the design of each blade can coordinate the forward bending motion of the body, effectively introducing the corrective force.
